feat(wm): add cmd to identify 'close to tray' apps

Issue #6 highlighted a workflow that I don't personally use, but I am
sure is common among other Windows users, which is to use the Close
button to minimize an application to the tray.

Since this is largely a configurable option in those applications
(Discord etc.), I have implemented a command for the user to identify
those applications themselves when configuring the window manager,
instead of adding them to the previous Vec of known multi-window
applications that need to be identified by default.

Close/minimize to tray applications can be identified either by their
class or their executable name.

I figure it is pretty important to know the rules defined on the window
manager instance, so I have exposed these on a new window_manager::State
struct which is now what get returns from the 'komorebic.exe state'
command.
